In this presentation, we will do assess the on-premises environment and determining what workloads and databases are ready to make the move and what can you do to improve their Azure readiness while reducing downtime during the migration. Planning and assessment plays a critical role in moving to the cloud. We would see wide range of resources and tools to get an assessment completed with ease while identifying workload dependencies with practical tips and tricks focusing on sizing and costs. And finally, we’ll assess the SQL instances and identify their readiness for Azure as well.

17. Trivia Question…
Real-World Example
In 2010, there was a new startup company
2 employees
Decided to use “the Cloud”
Launched app and overnight had 25,000 users
Within 3 months they hit 1 million users
That Company is...
?

19. Real Life Scenario from MS Site
The customer has a custom-built application based on an on-premises SQL Server that contains sensitive
intellectual property-related data. The application code has had some quirky development practices used in
the past, which have caused compatibility issues over the years during upgrades from SQL Server 2000 to
2005 to 2008 to, finally, 2012. Any changes made to this application are costly as the development work has
always been handled by a third party development team. The application also does many cross-database
queries for reporting and analysis reasons. A scheduled outage of the application would have a medium level
impact on the business but would be acceptable with some forward planning. The customer is not convinced
their current backup and recovery solution is reliable, with frequent failures occurring due to lack of free disk
space or hung backup agent processes. The customer would like to remove the headaches of these
operational tasks such as performing backups, patching, and version
upgrades.
